Thanks to its silent operation (no ticking) and optional sound signal, this Time Timer is perfect for use in sound-sensitive spaces. The red disk can be easily set with the centered control knob. The Time Timer MOD has a sealed battery compartment at the back.

The Time Timer MOD comes with a dark gray case as standard. Want a different color? You can easily replace the dark gray case with a case in a cheerful color.

The colored cases are sold separately as an accessory and are available in three colors: fuchsia, turquoise blue, and lime green. The Time Timer MOD operates on 1 AA battery (not included).
